More people died in World War One--aka the Great War--than in World War Two.
How do I know that? Grandad, my maternal grandfather told me. WWI was over when he was just a child, although for years I'm sure that for years afterward it haunted the converation of the grownups. He fought in Two.
It was very like him to point out that fact. To specify that the war he fought in could have been bigger, could have been worse. He was a kind man, and also a humble and unassuming one.
These qualities can lead to one being taken for granted. And I know that back then I didn't fully appreciate him. But even though he wasn't in the US armed forces--rather he was a member of the British Royal Navy--he's the vet I'm thinking of thise veteran's day.
